1 / 6 page  Features - Bipolar Hall effect latch sensor - 3.5V to 20V DC operation voltage - Open collector pre-driver - 25mA output sink current - Chip power reverse-connection protection - Operating temperature: C 125 ~ C 40 - Package: SIP3, SOT23 Applications - Rotor position sensing - Current switch - Encoder - RPM detection Pin Assignment (SIP3 package) ( SOT23 package) 1. VCC 2. GND 3. OUT 1. VCC 3. GND 2. OUT (Top view) General Description FH175 is a single-digital-output Hall-effect sensor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. While the magnetic flux density (B) is larger than threshold Bop, the OUT pin turns on (low). If B removed toward Brp, the OUT pin is latched “on” state prior to B < Brp. When B < Brp, the OUT pin go into “ off ” state.
